When you send a tracked email from your email inbox using the HubSpot Sales Office 365 add-in, or if you send a one-to-one email from a record, HubSpot will track email opens.
When you send a tracked email, HubSpot embeds an invisible one-pixel image into the email message once it is sent. When your recipient views the email and the images load, you will receive a notification that the email has been opened.
If the recipient's email client doesn't allow the track pixel to load, HubSpot will not be able to track the email open. HubSpot tracking can be deactivated in the following situations:
If the recipient has a very strict spam filter where they block any images or link tracking from loading in emails, your tracked email could be filtered as spam. However, email tracking tools are common, and the majority of email clients will not view your email any differently than before.
Please note: it's not possible to see whether a tracked email was forwarded to another recipient.
If you receive more email open notifications than expected for a specific tracked email, it may indicate that the email was forwarded or that you copied and pasted a previously sent email. Because of privacy and security concerns, when an email is forwarded, HubSpot defaults to telling you that the original sender opened the email again.
If you copied and pasted an email that you previously had sent, you also copy the original tracking pixel. The same tracking pixel would load for each recipient. It is recommended to send personalized emails, which you can create from scratch in the CRM or your mail client, or to use sales email templates.
Sometimes, a single tracking image will load multiple times because of how the recipient views their emails. For example, a user could be on a server that dynamically changes that user's IP address. If the image is loaded from multiple IP addresses, then the notifications may indicate that your emails were opened by multiple people.
Also, email clients like Outlook or Apple Mail have a preview pane as part of the inbox view. If recipients scroll over your email in their inbox, this can trigger an email open notification.
You may see a 'Someone' notification if one of the following occurs:
When sending tracked emails from your email client or from a record, you can track clicks on links included in the body of the email. Links are tracked by appending tracking to the end of any hyperlink included in your email. You can see click and open information in your HubSpot activity feed.
http://t.sidekickopen.com/e1t/c../../www.hubspot.com.../
The temporary redirection to the t.sidekickopen.com domain is necessary for HubSpot to register and track link clicks. The link will automatically redirect to the final URL destination (e.g. www.hubspot.com) when clicked.
